Principles

The whole operation can be automatically done with minimal work for the operator.

Back service

Once the LTMR is set up (at commissioning stage, for instance), the operator can save the LTMR’s memory into the LTMCUF memory through the HMI interface.

Restore service

In case of a drawer replacement, the operator just has to:

Rack out the drawer to be replaced.
Rack in a spare drawer. The LTMCUF installed in a fixed part of the panel will automatically detect the new LTMR and upload the recorded configuration to the new LTMR.
Acknowledge message for uploading the configuration to the LTMR (optional).

If LTMCUF is installed in the drawer itself, the operator has to remove it then install it in the spare drawer.

Copy/Paste a configuration on several LTMRs

LTMCUF can be combined with LTM9KCU to create a portable LTMCUF (see “Mounting a Portable LTMCU”) and upload the same configuration on several LTMR units:

Copy (by using Backup service) the configuration from the first LTMR unit.
Paste (by using Restore service) the configuration to the other LTMR units.
Through the HMI menu, set the network address for each LTMR unit, see .
